Standard Gear Pumps

Extrusion line synchronization made easy. With Standard Gear Pumps between your extruder and die you can directly dial in gauge control, eliminating extruder surge and screw beat at the die.

◆ Significant material savings
◆ Higher product quality
◆ Reduced scrap
◆ Regrind running
◆ Reduced load on extruder

Standard Gear Pumps

Extrusion line synchronization made easy. With Standard Gear Pumps between your extruder and die you can directly dial in gauge control, eliminating extruder surge and screw beat at the die. Extruder screws efficiently melt, mix and convey polymer, but are not as efficient at providing a consistent pressure and volume to the die. A gear pump, while not a mixing or melting device, is extremely efficient at building pressure and metering the polymer output.

The additional control of a Gear Pump installation also provides you with more production line flexibility, first by shortening start-up times on difficult materials and second, by processing multiple polymers with the same screw. The PLC Control closes the loop from pump inlet pressure to extruder drive while monitoring downstream pressure to eliminate any problems due to downstream line stoppage.

Features:
◆ Sizes available for all Products/Extruders

The Gear Pump is a positive displacement device which provides a linear output over a wide range of operating conditions.

A closed-loop drive control varies extruder screw speed to assure an adequate amount of polymer to the pump regardless of inlet pressure variations due to extruder surge and screw beat. Precise construction makes Gear Pumps extremely accurate volumetric metering devices. Each gear tooth “bucket” carries a precise, repeatable amount of polymer melt to the output side of the pump.

Integrate the Systems:
Put a Batte Screen Changer in front of the Gear Pump and further increase the productivity of the extrusion line, all from one company.

Gear Pump Options:
◆ Adapters
◆ Controls
◆ Drive Systems
◆ Mounting Stands
◆ Internal Fluid Channels (Heat/Cool)
◆ Manual Screen Changers
◆ Hydraulic Screen Changers
◆ Continuous Screen Changers
◆ Static Mixers
◆ Diverter Valves

Specifications:
◆ Maximum Operating Pressure: 345 bar (5,000 psi)
◆ Maximum Differential Pressure: 276 bar (4,000 psi)
◆ Maximum Temperature: 343˚C (650˚F)
◆ Transducer Ports: 4 locations in body for 155 size and larger pumps
Note: The pump body has internal channels to accept a heat/cool fluid media. The model option is utilized for heat sensitive polymers when very accurate temperature regulation is required.

Accurate Metering = Tighter Product Spec and Material Savings:
Gear Pumps operate at a constant speed and precisely meter polymer to die.

Improve Screw Efficiency and Increase Output:
Gear Pumps efficiently build pressure, thereby reducing extruder head pressure. By reducing extruder pressure, a screw can operate more efficiently and can convey more material.
